Hauv kev xam phaj nrog Syngenta's Herbicide US Technical Product Director, Dane Bowers, hauv kev sib tham txog yuav ua li cas cov khw muag khoom thiab cov neeg cog qoob loo yuav tsum teb rau lub caij 2021, nws tau hais txog nws cov lus coj mus tsev nyob rau ob peb xyoos dhau los: Kev tswj kev tiv thaiv tsis yog tib neeg tab sis ib tug kev teeb meem.Cov teeb meem coj tus cwj pwm.
"Los ntawm qhov kev xav ntawm kev xav, kuv xav tias peb muaj lub tswv yim zoo heev.Nws tau lees tias muaj kev sib tw-tsis txhob ua rau kuv yuam kev, tab sis peb txhua tus yog ib txwm ua neej nyob.Yog tias nws ua haujlwm rau peb, peb nyiam ua ib yam. "
Peb xav xav tias 2021 yuav coj rov qab los ntawm txhua yam, tab sis txog thaum ntawd, qhov no yog lub sijhawm zoo los nkag siab cov ntsiab lus ntawm kev tswj cov nroj tsuag.Tsuas pom qee cov nroj tsuag khiav tawm, tab sis tsis ntau dhau?Bowles tau hais tias: "Qhov ntawd yuav tsum yog ib qho canary nyob rau hauv lub thee mine.""Thaum twg koj pom qee qhov xwm txheej khiav tawm hauv cov tsiaj qus, koj yuav tsum xav txog seb kuv puas tau siv qhov kev pab cuam ntev dhau lawm, thiab seb kuv puas tsis suav nrog lwm qhov chaw txaus hauv kuv qhov kev pab cuam tshuaj tua kab.Yuav ua li cas lwm yam kev ntsuas kuv yuav tsum tau ua kom tsis txhob muaj qhov xwm txheej no?Feem ntau, thawj xyoo ntawm kev tawm tsam, koj tsis tshua xav tias koj muaj teeb meem, thiab tom qab ntawd thawj xyoo nws tau mob zuj zus hauv ob xyoos.Txog rau xyoo peb, nws yog kev puas tsuaj.Nws yeej yog ib kauj ruam tom ntej. "
Ntawm cov npe ntawm Bowers cov lus pom zoo rau lub caij tom ntej, thiab pom zoo los ntawm suav tsis txheeb agronomists, yog: 1) nkag siab txog cov teeb meem tshwj xeeb ntawm ib qho kev ua liaj ua teb, ntxiv rau cov tshuaj tua kab mob, thiab 2) nkag siab txog qhov yuav tsum tau pib ntxuav thiab ua kom huv si.Qhov no txhais tau hais tias siv cov tshuaj tua kab mob uas muaj zog ua ntej tshwm sim, thiab tom qab ntawd siv cov tshuaj tua kab mob uas muaj nyob hauv 14 mus rau 21 hnub tom qab.Cov tshuaj tua kab mob yuav tsum sib txuas ntau qhov chaw ua haujlwm kom txo tau txoj kev pheej hmoo ntawm cov nroj tsuag tiv taus.
“Qhov tseem ceeb tshaj plaws feem ntau yog qhov nyuaj tshaj plaws.Qhov tseeb, peb tau ua raws li txoj kev npaj vim tias tus nqi thiab ib puag ncig yuav tiv thaiv peb los ntawm kev txiav txim siab, "said Drake Copeland, FMC Technical Services Manager hauv Ohio, Michigan.
Wolfe tau hais tias: "Kuv xav tias thaum xav txog tshuaj tua kab mob, qhov kev pab cuam zoo nrog ntau hom kev ua yuav tsum yog ib qho ntawm koj thawj qhov kev xaiv."“Thaum koj tsav tsheb mus rau sab hnub poob thaum Lub Yim Hli thiab Lub Cuaj Hli, Qhov xwm txheej koj pom yog qhov yooj yim heev.Cov seem ntawm cov neeg no tau txo qis, thiab cov khoom seem ntxiv tau ntxiv rau lub caij.Lawv cov teb saib zoo heev thiab yuav luag tsis muaj dej tsuj.Cov neeg uas hla cov seem seem, Minnesota, Iowa thiab Dakota yuav tsum tau pom ntau yam cannabis thaum lub caij ntuj sov thiab lub caij nplooj zeeg ntxov.
Bowers tau hais txog qhov tseem ceeb ntawm kev siv tshuaj tua kab mob ua ntej germination hauv cov khoom dicamba, tshwj xeeb tshaj yog xav tias Dr. Larry Steckel ntawm University of Tennessee (L) thawj zaug tau txheeb xyuas Palmer tawm tsam dicamba.
Steckel tau sau rau ntawm nws qhov UT blog uas tos ntsoov rau 2021, tam sim no nws yog qhov tsim nyog los ua ntej siv cov khoom seem uas siv tau rau Palmer.Tsis tas li ntawd, kev ywj pheej yuav tsum tau siv tam sim tom qab siv dicamba kom tshem tawm kev khiav tawm.
Steckel tau taw qhia tias qhov no yog hom tshuaj tua kab thib tsib Palmer tau tsim tawm hauv Tennessee txij li xyoo 1994. "Yog tias peb faib 26 xyoo los ntawm 5 hom kev ua, kev ua lej yuav qhia tau tias cov nroj tsuag yuav txhim kho cov tshuaj tua kab mob zoo hauv 5.2 xyoo ntawm kev nthuav dav. siv."
Hauv Syngenta cov khoom lag luam, nws Tavium Plus VaporGrip thev naus laus zis dicamba premix muaj S-alachlor, uas muab peb lub lis piam ntawm cov haujlwm seem dua li dicamba ib leeg.Lub tuam txhab thov tias thaum cov tshuaj tua kab mob tom qab tshwm sim tau siv rau hauv cov tshuaj tua kab mob ua ntej tshwm sim (xws li Ciam 6.5 EC, BroadAxe XC lossis Prefix herbicides), "nws muab lub sijhawm zoo tshaj plaws kom dhau cov tshuaj tua kab mob tom qab tshwm sim hauv cov taum pauv hauv ib qho dhau los".
"Qhov no yog cov khoom lag luam muaj zog heev, txawm tias koj muaj tus yam ntxwv zoo li cas, koj tuaj yeem tswj cov nroj tsuag ua ntej soybeans, thiab nws muab qee qhov kev hloov pauv vim peb tsis tso tag nrho cov qe rau hauv cov khoom seem.Koj tuaj yeem rov qab los sai li sai tau los siv 15 pawg tshuaj tua kab mob, thiab nws kuj muaj tag nrho cov nyiaj xylazine. "Dr. Daniel Beran, Nufarm US Technical Services Director, hais rau CropLife®.
"Peb tuaj yeem tshem tawm qee qhov tsis paub tseeb thiab tsim kom muaj kev kub hnyiab thiab cov txheej txheem seem nrog qhov hloov tau zoo.Yog tias qhov zoo hloov pauv lossis cov cuab yeej siv hauv cov qoob loo raug txwv lossis qee lub sijhawm hloov pauv ntawm daim ntawv thov, ces yuav tsum muaj qhov zoo Cov tshuaj tua kab mob ntxiv yuav txo tau qhov nyuaj ntawm qhov kev hloov pauv no. "Nws tau taw qhia tias tam sim no rau Nufarm, nws yog qhov nthuav kom ua tus thib peb hauv kev ua haujlwm ntawm dicamba thiab 2,4-D thev naus laus zis.Moment-nws tso cai rau cov neeg sawv cev ntawm tuam txhab los pab cov khw muag khoom kom paub txog cov hauv paus.
Lwm yam khoom tshiab ua ntej cog hlawv tawm yog Reviton launched los ntawm Helm Agro hauv Tebchaws Meskas.Nws yog PPO inhibitor herbicide nrog cov khoom xyaw tshiab Tergeo rau cov pob kws, paj rwb, taum thiab nplej.Hauv ntau tshaj 700 North American cov khoom tsim kev sim thiab kev tswj hwm kev tshawb fawb, Reviton tau ua pov thawj tias "tshaj li 50 broadleaf thiab nyom nyom (xws li ALS, triazine thiab glyphosate resistant hom) yog qhov zoo heev rau kev kub hnyiab tswj kev ua tau zoo.
Nrog rau cov khoom lag luam poob qis, Copeland tau pom cov qoob loo zoo (cov qoob loo nce ntxiv) thiab cov xwm txheej tsis zoo (txo cov tshuaj tua kab mob).
Nws tau hais tias: "Cov tshuaj tua kab mob seem hauv daim ntawv thov tom qab yog tus yuam sij rau kev tswj xyuas cov nroj tsuag seem uas yuav tsum tau ua rau cov qoob loo raug kaw rau lub caij ntuj sov," nws hais ntxiv, "Tsis tas li ntawd, cov tshuaj tua kab seem yuav raug tsis quav ntsej hauv txhua daim ntawv thov.Kev nce cov noob xa rov qab mus rau hauv av cov noob hauv txhab nyiaj thaum kawg yuav tso nyiaj ntau dua los siv rau kev hla ntxiv hauv thaj teb los ntxuav qhov kev ntxhov siab. "
Copeland tau hu rau Purdue University los ua kev tshawb fawb, uas pom tias qhov seem seem sib tshooj yog tib txoj hauv kev los txo cov kev tswj hwm ntawm thawj xyoo noob qoob loo.Kev kho mob yam tsis muaj kev xa tawm ntawm cov tshuaj tua kab mob sib tshooj nrog ntau qhov chaw ntawm kev ua tau ua rau muaj kev nce ntxiv hauv qhov ntom ntom ntawm cov dej hemp hauv cov noob txhab nyiaj.Nyob rau hauv sib piv, cov txheej txheem mus sij hawm ntev tom qab tshwm sim residual siv overlapping residues kom txo cov dej kub nce 34% (saib daim duab hauv qab).
Nws hais tias: "Cov ntaub ntawv zoo li no tuaj yeem pab peb cov khw muag khoom thiab agronomists tham nrog cov neeg cog qoob loo.""Lawv tuaj yeem hais tias, 'Kuv paub lub sijhawm nyuaj, tab sis yog tias peb xav ua kom tiav lub neej yav tom ntej ntawm koj cov liaj teb, ces peb tsis tas yuav txiav ib yam dab tsi, txawm nyob hauv lub Hoobkas lossis sab saum toj, peb tuaj yeem txo qhov seem. tshuaj tua kab mob.'””
Raws li Dr. Bob Hartzler tau piav qhia hauv Iowa State University Integrated Pest Management Blog: "Vim qhov nthuav dav ntawm cov nroj tsuag tshuaj tua kab mob sai sai, Iowa txoj kev tswj cov nroj tsuag tam sim no muaj kev pheej hmoo txhawm rau txhawm rau tswj cov tshuaj tua kab kom zoo, ob yam yuav tsum tshwm sim: 1) txais kev tswj cov nroj tsuag sib xyaw;2) hloov lub hom phiaj ntawm kev tswj cov nroj tsuag los ntawm kev tiv thaiv cov qoob loo yields kom txo qhov luaj li cas ntawm cov nroj tsuag nroj tsuag.Thawj qhov yuav tsum tau ua yog hloov tus cwj pwm, qhov thib ob yuav tsum tau hloov tus cwj pwm. "
Ntxiv nrog rau cov nqi pheej yig dua cov khoom seem, Syngenta's Bowers kuj tau ceeb toom txog "cov tshuaj cuav" los khaws nyiaj ntsuab.
Bowers tau tshaj tawm cov qauv kev ntsuas kev ruaj ntseg uas ua los ntawm Syngenta ntawm cov khoom siv dav dav.Yog tias cov khoom xyaw nquag tsis raug tsim kom raug, AI tuaj yeem tawm tsam ib leeg thiab ua rau cov tshuaj tua kab muaj.Thaum tus neeg cog qoob loo siv cov khoom lag luam uas tsuas yog 80% ntawm AI ua haujlwm, nws yuav tsis tsuas ntsib cov teeb meem sib xyaw, tab sis nws kuj tseem tuaj yeem siv nws ntawm tus nqi qis dua li daim ntawv lo thiab cov tshuaj tua kab mob qis dua li qhov xav tau.
Bowers tau hais tias ib qho piv txwv tshwj xeeb yog tias tib neeg nyiam siv cov qauv dav dav, uas yog kev sib xyaw ntawm AI S-metolachlor hauv Dual II Magnum thiab AI mesotrione hauv Callisto, uas Syngenta tuaj yeem muab ntau yam pob kws premixes, xws li Acuron.Nyob rau hauv premix ntawm mesotrione thiab S-metolachlor, "Yog hais tias S-metolachlor tsis raug tsim, nws yuav degrade cov mesotrione muaj."
Bowers tau hais ntxiv tias: "Nws yog qhov kev txiav txim siab zoo dua los siv ob peb las pem hauv ntej thiab kho cov phiaj xwm tshuaj tua kab kom muab cov txiaj ntsig zoo dua, kom cov bushels ib acre zoo dua.Thaum cov khoom lag luam qis dua, tsim ntau ntau ntau bushels yog koj tus yuam sij.Peb yuav tsis txuag txoj kev vam meej, yog li peb yuav tsum muaj kev sib npaug ntawm kev siv nyiaj txiag, tab sis peb yuav tsum xyuas kom meej tias koj tau txais txiaj ntsig ntawm koj cov peev txheej thiab cov nyiaj rov qab los ntawm cov nyiaj.
